My wife's 01 4.4 has 138k miles on it and I have had to do many window regulators, coolant res, radiator, and just recently the transfer case and front drive shaft. SES light is on, DSC ABS lights are on, and Im in the same position. I just put almost $6k in it to have the transfer case and front drive shaft replaced and now I worry about the tranny. The tranny shifts and seems to run fine but I just do not feel like I can trust it to go anywhere outside of a trip to the grocery store.
